Abstract

A behind the detector sounder has a base plate and walls which define mechanical horns having throats which open into a space at the centre of the base plate. The mouths of the mechanical horns are at the outer periphery of the base plate and the walls bound sound paths which are longer than the straight line distance from the throat of each mechanical horn to the mouth of that mechanical horn.
